Example Usage Scenarios:

The following are example usage scenarios for this profile:

• Query for a Patient’s current or historical problems and health concerns
• Record or update a Patient’s problems and health concerns

Mandatory and Must Support Data Elements

The following data-elements must always be present (Mandatory definition) or must be supported if the data is present in the sending system (Must Support definition). They are presented below in a simple human-readable explanation. Profile specific guidance and examples are provided as well. The Formal Views below provides the formal summary, definitions, and terminology requirements.

Each Condition Must Have:

1. a category code of “problem-list-item” or “health-concern”
2. a code that identifies the condition
3. a patient

Each Condition Must Support:

1. a clinical status of the condition (e.g., active or resolved)
2. a verification status
3. additional health status/assessment categories
4. a date of diagnosis*
5. abatement date (in other words, date of resolution or remission)
6. a date when recorded*

*see guidance below

Profile Specific Implementation Guidance:

• For Encounter Diagnosis use the US Core Condition Encounter Diagnosis Profile.
• For USCDI v2+, the applicable vocabulary standards for Problems/Health Concerns are SNOMED CT and ICD-10-CM. For general guidance on extensible binding to coded data, review this section in the General Requirements page.
  • The US Core Condition Codes supports ICD-9-CM for historical purposes only. ICD-10-CM is available and SHOULD be used as the primary code for current encounter diagnoses.
• See the Screening and Assessments guidance page for more information when exchanging Social Determinants of Health (SDOH) Problems/Health Concerns.
• If Condition.category contains a Problem List item category (problem-list-item), Condition.clinicalStatus SHOULD be present.
• *There is no single element in Condition that represents the date of diagnosis. It may be the assertedDate Extension, Condition.onsetDateTime, or Condition.recordedDate.
  • Although all three are marked as Must Support, the server is not required to support all.
  • A server SHALL support Condition.recordedDate.
  • A server SHALL support at least one of assertedDate Extension and Condition.onsetDateTime. A server may support both, which means they support all 3 locations.
  • The client application SHALL support all three elements.

Summary

Mandatory: 3 elements
Must-Support: 11 elements

Structures

This structure refers to these other structures:

• US Core Patient Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient)

Extensions

This structure refers to these extensions:

• http://hl7.org/fhir/StructureDefinition/condition-assertedDate

Slices

This structure defines the following Slices:

• The element Condition.category is sliced based on the value of pattern:$this

Quick Start

Below is an overview of the required Server RESTful FHIR interactions for this profile - for example, search and read operations - when supporting the US Core interactions to access this profile’s information (Profile Support + Interaction Support). Note that systems that support only US Core Profiles (Profile Only Support) are not required to support these interactions. See the US Core Server CapabilityStatement for a complete list of supported RESTful interactions for this IG.

• The syntax used to describe the interactions is described here.

• Servers providing access to problems and health concern data can use US Core SMART Scopes for:
  • resource level scopes (for example, patient/Condition.rs)
  • granular scopes (for example, patient.Condition.rs?category=http://terminology.hl7.org/CodeSystem/condition-category|problem-list-item and patient.Condition.rs?category=http://hl7.org/fhir/us/core/CodeSystem/condition-category|health-concern`).
• See the General Requirements section for additional rules and expectations when a server requires status parameters.
• See the General Guidance section for additional guidance on searching for multiple patients.

Mandatory Search Parameters:

The following search parameters and search parameter combinations SHALL be supported:

1. SHALL support searching for all conditions including problems, health concerns, and encounter diagnosis for a patient using the patient search parameter:

   GET [base]/Condition?patient={Type/}[id]

   Example:

   1. GET [base]/Condition?patient=1137192

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient (how to search by reference)

2. SHALL support searching using the combination of the patient and category search parameters:

   GET [base]/Condition?patient={Type/}[id]&category={system|}[code]

   Example:

   3. GET [base]/Condition?patient=1032702&category=http://terminology.hl7.org/CodeSystem/condition-category|encounter-diagnosis

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and category. (how to search by reference and how to search by token)

Optional Search Parameters:

The following search parameter combinations SHOULD be supported:

1. SHOULD support searching using the combination of the patient and clinical-status search parameters:

   GET [base]/Condition?patient={Type/}[id]&clinical-status=http://terminology.hl7.org/CodeSystem/condition-clinical|active,http://terminology.hl7.org/CodeSystem/condition-clinical|recurrance,http://terminology.hl7.org/CodeSystem/condition-clinical|remission

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and all "active" statuses (active,relapse,remission). This will exclude diagnoses and health concerns without a clinicalStatus specified. (how to search by reference and how to search by token)

2. SHOULD support searching using the combination of the patient and category and clinical-status search parameters:

   GET [base]/Condition?patient={Type/}[id]&category={system|}[code]&clinical-status=http://terminology.hl7.org/CodeSystem/condition-clinical|active,http://terminology.hl7.org/CodeSystem/condition-clinical|recurrance,http://terminology.hl7.org/CodeSystem/condition-clinical|remission

This will exclude diagnoses and health concerns without a clinicalStatus specified. (how to search by reference and how to search by token)

3. SHOULD support searching using the combination of the patient and category and encounter search parameters:

   GET [base]/Condition?patient={Type/}[id]&category={system|}[code]&encounter={Type/}[id]

   Example:

   1. GET [base]/Condition?patient=1032702&category=http://terminology.hl7.org/CodeSystem/condition-category|encounter-diagnosis&encounter=1036

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and category and encounter. When category = "encounter-diagnosis" will return the encounter diagnosis for the encounter. (how to search by reference and how to search by token)

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and code. (how to search by reference and how to search by token)

5. SHOULD support searching using the combination of the patient and onset-date search parameters:
   • including support for these onset-date comparators: gt,lt,ge,le
   • including optional support for AND search on onset-date (e.g.onset-date=[date]&onset-date=[date]]&...)

   GET [base]/Condition?patient={Type/}[id]&onset-date={gt|lt|ge|le}[date]{&onset-date={gt|lt|ge|le}[date]&...}

   Example:

   1. GET [base]Condition?patient=555580&onset-date=ge2018-01-14

   Implementation Notes: Fetches a bundle of all Condition resources for the specified patient and date. (how to search by reference and how to search by date)

6. SHOULD support searching using the combination of the patient and asserted-date search parameters:

   • including optional support for AND search on asserted-date (e.g.asserted-date=[date]&asserted-date=[date]]&...)

   GET [base]/Condition?patient={Type/}[id]&asserted-date={gt|lt|ge|le}[date]{&asserted-date={gt|lt|ge|le}[date]&...}

   Example:

   1. GET [base]Condition?patient=555580&asserted-date=ge2018-01-14
